The lever 18 is pivoted as at 21'to the handle member 5, rearwardly. of the guide '16, and is formed with an extension in the form of a wire-cutting blade 22 which cooperates with a sharpenededge 23 provided at one side of a notch formed in suitable clamping jaw 25 is rigidly fixed be I tween the bifurcations of the handle member for cooperating with a pivotal wire-clamping member 26 to form a forward wire clamp. The pivotal clamping member 26 is disposed and pivoted between the bifurcations of the handle member inwardly of the jaw 25 and has a rearwardly extending figure piece 27 adapted to be lifted for releasing the clamp, the latter being normally operative through the, provision of a tension spring 28 attached to the handle member and to the clamp member 26.

From the above description it will be seen that a pair of rear wire clamps are provided,

" one of the same being disposed at each side of the handle member so that the wire may be clamped at the upper side of the handle irrespective of which side of the handle is disposed upwardly so that engagement of the wire with the present device is made easy and the possibility of encountering difficulty in the use .of the improved implement is eliminated. Also, the provision of .the lever 18 adjacent the hand-hold 19 enables operation of the handle and the rear clamps by means of one hand, thereby leaving the other hand free for any other desired purposes, such as effecting positioning of the wire in the respective clamps.

Among the many uses to which the present implement may be put will be mentioned the following:

The claw may be employed for pulling staples, etc. Any one of the wire clamping devices may be engaged with a runner-wire and the claw end of the implement applied to a post as a fulcrum and the device then. used as a lever to stretch the wire; The ad jacent ends of the broken wire may be engaged with either one of the rear clamping devices and also with the front clamping device so that if the implement is then turned around the wire as an axis, the wires will be intertwisted for connecting the same.

While I' have shown the implement as composed of individual members including a handle member with the several fixed clamping jaws attached thereto, it is apparent that these may be formed integral without departing from the spirit. and scope of i the invention as claimed.

lVhat I claim as new is:

An implement of the class described comprising a handle member, a pair of spaced parallel wire clamping members pivoted to the handle member at opposite-sides of the latter, said handle member projecting forwardly beyond said clamping members and having rigid jaws upon opposite sides of its projecting portion to form shoulders cooperating with the forward ends of said clamping members to produce wire clamps at opposite sides of the handle, the projecting portion of the handle being bifurcated, and a pivotal wire clamping member mounted in the bifurcation of the handle, and a fixed jaw member mounted in the bifurcation of the handle member forwardly of said pivotal wire clamping member and cooperating with the latter to provide a forward wire clamp, said pair of parallel clamping members being of bell crank form in elevation and connected at their rear ends by means of a circular connection, a guide fixed upon the handle member rearwardly of said pair of clamping members, a link slidable through said guide and having its forward end piv otally engaged with the circular connecting member, a spring encircling said link between the guide and a pair of clamping members for normally maintaining the latter in clamping position, and an angular lever pivoted to the handle member and to the link rearwardly-of the guide and adapted to be grasped by one hand of the operator together with the adjacent portion of the handle member for releasing said pair of clamping members against the action of said sprin FRANK R.
